PS9821-2 - PHOTOCOUPLER

Download the PS9821-2 datasheet PDF. This datasheet also covers the PS9821-1 variant, as both devices belong to the same photocoupler family and are provided as variant models within a single manufacturer datasheet.

General Description

The PS9821-1 and PS9821-2 are active-low type high-speed photocouplers that use a GaAlAs light-emitting diode on the input side and a photodetector IC that includes a photodiode and a signal processor on the same chip on the output side.

Key Features

  • Low power consumption (VCC = 3.3 V).
  • Pulse width distortion (⏐tPHL.
  • tPLH⏐ = 35 ns MAX. ).
  • High common mode transient immunity (CMH, CML = ±15 kV/μs MIN. ).
  • 40% reduction of mounting area (5-pin SOP × 2).
  • High-speed (15 Mbps).
  • High isolation voltage (BV = 2 500 Vr. m. s. ).
  • Open collector output.
  • Ordering number of tape product : PS9821-1-F3, F4: 1 500 pcs/reel : PS9821-2-F3, F4: 1 500 pcs/reel.

PHOTOCOUPLER PS9821-1,-2 HIGH CMR, 15 Mbps OPEN COLLECTOR OUTPUT TYPE 8-PIN SSOP (SO-8) 3.3 V HIGH-SPEED PHOTOCOUPLER −NEPOC Series− DESCRIPTION The PS9821-1 and PS9821-2 are active-low type high-speed photocouplers that use a GaAlAs light-emitting diode on the input side and a photodetector IC that includes a photodiode and a signal processor on the same chip on the output side. The PS9821-1, -2 are designed specifically for high common mode transient immunity (CMR) and low pulse width distortion, PS9821-2 is suitable for high density applications. FEATURES • Low power consumption (VCC = 3.3 V) • Pulse width distortion (⏐tPHL−tPLH⏐ = 35 ns MAX.) • High common mode transient immunity (CMH, CML = ±15 kV/μs MIN.
